You should be able to use any single groove FE pulleys including 352,360 and 390 truck motors. Salvage yards and recycling places usually have complete junk motors around.I think some of the cobra parts places like cobra restorers sell them new .I wouldnt be suprised if they aren't still serviced by ford.
I used a set of march pulleys on my motor which look like stock after I painted them to hide the ugliness of billet,lol.
good luck,Tim
